Graceline Court

This residential 17 story Harlem development is adjacent to a landmark building – the Malcom Shabazz Mosque. It consists of 750 tons of structural steel. The particularity of this structure resides in the fact that, as it can be observed in the renderings, starting on the 6th floor, the building is cantilevered out over the mosque (more than one third of each floor area will be over the adjacent building). This was realized by using three two-story high special metal trusses designed to support the load of the cantilevered part of the building and transmit it to the foundation. Extensive 3D analysis of the building behavior under wind and seismic loads was performed; also, special connections and steel shapes for the trusses were developed. Wes Consultants provided steel detailing services for this project.
